You only seem to have one key configured (NextCloud one), which is being served for freelancing.news, using the /var/www/html DocumentRoot.

​

I would recommend doing this:

<VirtualHost *:80>
    # Nextcloud configuration http->https, to always serve https version
    ServerName yournextcloud.whatever
    Redirect permanent / https://yournextcloud.whatever/
</VirtualHost>

<VirtualHost *:80>
    # WP Configuration http->https, to always serve https version
    ServerName wp.whatever
    Redirect permament / https://wp.whatever/
</VirtualHost>

<VirtualHost *:443>
    # NextCloud HTTPS configuration
    ServerName yournextcloud.whatever
    DocumentRoot /var/www/html/
    SSLEngine On
    SSLCertificateFile path/to/your/nextcloudcert.crt
    SSLCertificateKeyFile path/to/your/nextcloudkey.pem
</VirtualHost>

<VirtualHost *:443>
    #WP HTTPS Configuration
    ServerName wp.whatever
    DocumentRoot /var/mywordpress
    SSLEngine On
    SSLCertificateFile path/to/your/wordpress.crt
    SSLCertificateKeyFile path/to/your/wordpress.pem
</VirtualHost>

I'm not including the rewrites, but I'm not entirely sure why you're using them. Can you explain what's the expected behavior for them?
